Supernovae are some of biggest, baddest explosions around. In this episode, we will learn what causes these cosmic catastrophes, and the various types of supernova that may manifest depending on the type of star that precedes it.

Lately there has been talk of a new largest galaxy, named Alcyoneus, which is said to boast a diameter of 16.3 million light years. But is that what's really being proposed in the original paper detailing the discovery? And if Alcyoneus is not the new largest galaxy, then how does it compare with the previous record holder IC 1101?

On December 25th 2021, NASA launched their most advanced and expensive telescope ever- the James Webb Telescope, which has been in development for over 30 years. From distant stars and planets, to the dawn of time itself, this telescope will transform our view of the universe, as we usher in a new age of astronomy- the age of Webb.

The Andromeda Galaxy is our nearest neighbouring spiral galaxy, around 2.5 million light years from Earth. At twice the size and more than double the number of stars, Andromeda represents a larger and even more mysterious galactic kingdom than our own. Today, we will be taking a journey to this galaxy.

Ever wonder what it would be like to fly all the way to the edge of space? Well in this episode, we'll be doing just that. We will embark on a tour of our universe- venturing deep into the darkness, uncovering the most jaw-dropping landmarks along the way. This is our journey to the edge of the universe.

Journey to the Edge of the Universe - No Music

Our view of the cosmos is limited to the observable universe- the slice of space containing all the galaxies that can be seen from Earth. But what we perceive to be the edge of our universe is not the actual edge of the universe- with most scientists in agreement that more space lies hidden beyond what we're able to see. Last time out, we travelled to the very edge of our observable universe. But today, we will be going even farther, as we wade out into the darkness of the unobservable universe.

The Earth, the blue planet. An ancient oasis of life suspended in the darkness of space. As rich and life-supporting as the Earth is today, it was once nothing more than a column of dust, dancing inside a scorched cyclone of stellar gas. And just how we as humans managed to emerge from this ancient dust makes up the topic of this video. So join us, as we wind the cosmic clock backwards almost five billion years, from you and I today, all the way back to the birth of the solar System, back to when Earth was nothing more than a burning, barren wasteland.

How did Earth get its moon? Why is Mercury so close to the sun? Why does Uranus orbit on its side? The answers to all of these questions are the many collisions that ravaged the early Solar System.

Each of our neighbouring worlds bears scars which echo their violent past. And in this video, we will examine a number of the most significant collisions, which played a pivotal role in building up the Solar System as we know it today.

From studying the dusty surface of Mars, to plunging into the atmosphere of Venus, over the last 60 years, we've launched scores of probes into space on trajectories to visit each of the terrestrial planets. But for all the fascinating discoveries made on the way, humanity's journey towards the stars started out in a much darker place- a battlefront between the world's then two great competing superpowers. And in this first episode on my new series on probes, we will revisit this space race, and the major milestones on route to visiting each of the terrestrial planets.

Far beyond the reaches of the four rocky planets, we find our Solar System's showpiece worlds- the two gas giants, Jupiter and Saturn. As the two largest planets, both are tantalising targets for probes exploring the planetary neighbourhood. But both lie significantly farther from the sun than the Earth and its terrestrial neighbours. But in the early 1970s, the technology for deep space voyages was primed, and missions to both Jupiter and Saturn ensued.

Those missions make up the topic of our track today, in this second episode of our trilogy of Probes that Studied the Solar System.

Journey To The Gas Giants - No Soundtrack

Of all the spacecraft to have visited other worlds, there are two which have travelled further than any other, discovering more about the Solar System than their inventors ever could have imagined. They are the legendary pair of Voyager Probes; still the only spacecraft ever to have visited the Ice Giant planets, Uranus and Neptune. And the story of their 40 years in space makes up the topic of our video today- from the gas giants, to the ice worlds, and then out into the depths of interstellar space...
